Oklahoma Pit and Fissure Sealants State Practice Exam

Resin material for sealants can be categorized as which of the following?

1. Colorful or monochrome

2. Filled or unfilled

3. Reusable or disposable

4. Liquid or solid

The correct answer is: Filled or unfilled

Resin materials for sealants can be categorized as filled or unfilled based on the presence or absence of particulate additives. Filled resin sealants contain a variety of materials, such as glass or silica, which enhance their mechanical properties, provide wear resistance, and improve the sealing capabilities by making them more viscous. In contrast, unfilled resin sealants lack these additives, resulting in a different texture, flowability, and application characteristics. This distinction is crucial in dental practice, as the choice between filled and unfilled sealants can affect their longevity, effectiveness, and suitability for different clinical situations. For example, filled sealants may provide better abrasion resistance and durability, making them ideal for high-stress areas in the mouth. Understanding these categories allows dental professionals to make informed decisions about which sealant to use based on the specific needs of their patients. Other options, while describing different aspects, do not reflect the most relevant classification for pit and fissure sealants. Colorful or monochrome addresses aesthetics without impacting functionality, reusable or disposable refers to the applicators rather than the resin itself, and liquid or solid encompasses a broader range of materials beyond sealants. Therefore, filled or unfilled remains the accurate categorization of resin materials for sealants
